BlackBerry 10 Device Simulators

If you want to test your app for a specific version of the BlackBerry 10 OS, you can download the BlackBerry 10 device Simulator for that OS version here.
To ensure your app is tested on the correct OS, download the Simulator version that has a build number matching the BlackBerry 10 OS version number (accessible from the Settings > About > OS screen on your BlackBerry 10 device).
